Truths and Lies Truth is mighty and will prevail. There is nothing wrong with this, except that it ain't so. A lie can travel halfway around the world while the truth is putting on its shoes. Mark Twain (1835 – 1910)

Do You Believe Global Warming is NOT a Serious Threat to our Planet? If so raise your hand. Do believe the planet is undergoing an unusual level of surface and ocean warming? Do you think human activities significantly responsible? Are any of you among those, including some scientists, who are skeptical that burning fossil fuels and cutting forests threaten serious changes in climate?

Climate and Weather Climate is what you expect; Weather is what you get. Climate is what you affect; Weather is what gets you. -- Myles Allen, Professor of Geosystem Science, Oxford University

How we shall Proceed Understand the publics limitations in understanding of complex science issues and voters are slow to direct policy action. Importance of addressing the climate change problems One set of data on global warming – – affect of climate change on oceans Why many people reject climate change evidence. What we can do about it.

Do Americans Accept Established Science? 39 % do not accept biological evolution 61 % cannot name a fossil fuel 42 % believe people and animals have been this way since the beginning of time. 43 % believe human and dinosaur fossils prove that both lived at the same time. 20 % say the sun circles around the earth.

13
What Do Americans Believe about Science? They admire scientists but do not understand how scientists arrive at their conclusions. When scientists disagree, the public assumes – neither is right or – the one whose view best fits their culture, beliefs, and interests is right. 42 % do not think climate change is serious

Why do many people reject the evidence that climate change is real and due, in large part, to human activities? Is it fear from the message? Distrust of the messenger? Politics? Ideology or culture? Economic self-interest or Something else? Since 1934 the Tobacco Industry denied the health dangers of smoking and millions of Americans died needlessly. What does it take to restore fact-based policy making to our democracy?

25
Consequence of ignoring or denying science and health data: Tobacco Surgeon Generals 1964 report: excessive smoking is causing a lung cancer epidemic. Tobacco companies continued to win law suits with arguments about attribution, while knowingly conspiring to suppress and deny the scientific and medical evidence. By 1998 Plaintiffs began to win suits when judges demanded release of documents showing evidence of tobacco company conspiracies.

27
Denial of Strong Science – Protecting Financial & Political Interests Misinformation and propaganda, masquerading as science and fueled by heavy spending, are injected not only into media accounts but into debates in the Congress. Now the deniers want you to believe burning fossil fuels are not primary cause of global warming or dangerous climate change.

Confidential memo (seen by Guardian) calls for climate change skeptics to turn American public against wind power. A number of right-wing organizations, including Americans for Prosperity, which is funded by the billionaire Koch brothers, are attacking Obama for his support for solar and wind power. The American Legislative Exchange Council (ALEC), which also has financial links to the Kochs, has drafted bills to overturn state laws promoting wind energy.wind power

Michael Mann has successfully fought off an attempt by a pro-industry think-tank to gain access to thousands of his private emails. There is similar legal action against the NASA scientist James Hansen. His research, demonstrating a recent sharp rise in warming, is one of the most easily understood representations of climate change – and has also infuriated those opposing action on global warming.

31
What Can Be Done to Reduce Global Warming and Climate Change? New sources of renewable energy must be developed and adopted, globally. Ultimately those who are responsible for oil, gas, and coal that cause global warming must be induced, by law or markets, to reduce their activities. But public engagement must come first. What can scientists do to convince the public to support public policies to slow climate change?

32
Seeking Rational Government Polices The Union of Concerned Scientists has created a new Center for Science and Democracy, to help scientists to seek more rational public policies. Issues like climate change will be discussed by forums of scientists, politicians, industry executives, social scientists, and the public seeking workable, long-term solutions.

33
Is The Enlightenment a Realistic Model? Our nations founders were committed to unleashing the power of reason to advance knowledge and to build an effective, responsive and trust-worthy government. The early voters were, like the founders, land- owning, white, men well-educated in the philosophy of the Enlightenment.

34
Do science and democracy rely on common principles? Science offers a model that can help restore our governments ability to make decisions through constructive debates and evidence-based decisions. Thats because the progress of science is based on transparency, evidence, accountability, and trust. These must also be the basic principles of a democratic government if it is to be legitimate, effective, credible and trusted by the electorate.

35
Why Many People Deny Science and Reality Chris Mooney argues that Motivated Reasoning is a physical property of the brain, when emotions are wired to take control of rational thinking. ….Good arguments will only win the day when people dont have strong emotional commitments that contradict them. …Cold reasoning (rational, unemotional) is very different from hot reasoning (emotional, motivated). Research shows the more educated are even harder to dissuade from their illusions than the poorly educated. The Enlightenment – the philosophy of the inevitable dominance of rationality -- is an illusion. Dan Yankelovich and other scholars of this issue would agree. Chris Mooney, The Republican Mind, John Wiley, 2012.

36
Engaging the Public An informed public is essential for democracy to work and is grounded in our political tradition. Public is now confused and conflicted about climate change. How to effect a transition from raw opinion to considered, thoughtful judgment? Dan Yankelovich is the expert on this question.

37
Correcting Assumptions on Public Opinion on Technical Issues On complex and emotion-laden issues, technical and economic facts are often secondary. The message scientists transmit is not the message the public hears. The message is distorted by – Inattention – Lack of interest – Denial – Lack of context – Bias from personal interests – Science concepts are counter intuitive (eg. statistics)

39
What Can Scientists Do to Promote Sound Rational Government and Public Policies? Learn the lessons from 40 years fighting the Tobacco Industry. Meet the challenge of climate change denial and other attacks on science and on rational government. Expose non-profits who attack scientists & science illegally. Understand and engage the publics learning curve. Improve public education and encourage youth to take home what they learn. Engage the rational, responsible leaders in industry. Support the Center for Science and Democracy in these tasks.

Truth and Lies Truth is mighty and will prevail. There is nothing wrong with this, except that it ain't so. A lie can travel halfway around the world while the truth is putting on its shoes. Mark Twain (1835 – 1910) No lesson seems to be so deeply inculcated by experience of life as that you should never trust experts. If you believe doctors, nothing is wholesome. If you believe theologists, nothing is innocent. If you believe soldiers, nothing is safe. – Lord Salisbury, (Prime Minister of England 1885 – 1892, 1895 -- 1901) Science, like any field of endeavor, relies on freedom of inquiry; and one of the hallmarks of that freedom is objectivity. Now, more than ever, on issues ranging from climate change to AIDS research to genetic engineering to food additives, government relies on the impartial perspective of science for guidance. – George H. W. Bush (President of the USA, 1989 – 1993)

President Obamas Commitment to Pragmatic & Fact-based Governance A major emphasis during the 2008 campaign OMB Directive to all Executive Departments and Agencies (May 18, 2012 by J. D. Zients, OMB Director): – Since taking office, the President has emphasized the need to use evidence and rigorous evaluation in budget, management and policy decisions to make government work effectively.…Where evidence is strong, we should act on it. Where evidence is suggestive, we should consider it. When evidence is weak, we should build the knowledge to support better decisions in the future.
